CPU Voltage, is it safe?

[FirstNewbie]

So i overclocked my i5-7600k to 4.5ghz with 1.385 voltage. How do I know this isn't to much and how do I know when i've hit the correct voltage level?

Lower your voltage until the system is no longer stable, then crank it back up a notch or two. That voltage, while not entirely unsafe is a bit high for only a 4.5GHz OC. I would think you could get away with around 1.3v. 1.385v should be good for around a 5GHz OC give or take.

Ah nice, when we talk about cranking it up a notch or two are we talking like 1/100 or 1/10?

Ex: If the CPU crashes at 1.100, would 1.110 be enough or is it to low/high?

Thanks for the awesome answer btw, love this community ! <3

Yes, your example is fine, set in small increments and stress test for stability in between.

Thanks man

Also watch your CPU core temperatures while you are stress testing your overclocks. Keep in mind the cpu may run hotter in the summer, unless you keep the room at the same temp as winter. Some people set up a winter overclocking profile and a summer one.

Yeah, well I live in Sweden so we don't usually get temperatures over 25°C (77°F) in summers so it's not that big of a problem.

I've found a sweetspot at 1.305v for 4.5ghz on the 7600k. After 1h of 100% load (aida64 extreme), the core temperatures are stable at 55-60°C (131-140°F) and the cpu fan average 1050rpm during the hour.

You are lucky with the summer temperatures! I live on the Texas Gulf Coast and in the summer it will be in the 90's F for 3-4 months. Right now it is 93 F at 6:23 in the evening. I have a supplemental air conditioner in my 2nd story office and between that and my central air conditioning I struggle to keep the daytime temperatures below 80 F.

Can you set up a fan speed profile to increase the speed as the core temp rises? Although your stress test temps are good.

Haha I get the summer profile now

Yeah it's already set that way, it was an option in the BIOS, right now, just streaming a movie the cpu fan averages 450rpm
